<p class=""><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)">Thank you
for pointed it out. I have understood who the ExternalAuth works.</span></p>

<p class=""><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)">The subsequently
question is that how the SP communicates with Users? Like Tomcat keeping session
with setting cookie JSESSIONID, is there one mechanism used between SP and
Users? </span></p>

<p class=""><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)"> </span></p>

<p class=""><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)">Thanks.</span></p>
